**What can trigger an Interac Fraud alert?**

* Interac does not share the reason for flagging a transaction for fraud.
* Here are some situations that may trigger a transaction to be in-review for fraud:
  * When the same person attempts multiple transactions on the same day
  * When the email used belongs to a domain that is recently registered
  * When the person attempts to complete the payment using a suspicious browser fingerprint (IP address, browser, device, time-zone)
  * When the person attempts to deposit with multiple bank accounts
